I'm Creating a Spice model with the TPD3S014_TRANS device. When I pulse it on/off is seems to not have the Reverse Current Blocking that is featured in the datasheet for the TPD3S014-Q1.

Hi Kevin,

Thank you for the feedback. I'll relay this answer to the designer.

Do you get the spice model from the product page? Could you provide a picture showing your simulation circuit and the reverse current when device is off?

Best Regards,

Ke Wang

Hi Ke,

I pulled the Spice model right from the "Pspice for TI" library. I have a basic SCH I can show with the input being turned on/off and the output capacitor being drained back out through the device.

With the diode D2 in:

without D2 in:

Not the positive current spike (blue) of the current going back into the device after being turned off.

Kind Regards,
Kevin
